Abstract

Various temperatures were tested for maintaining Pteromalus puparum (L.) adult parasites in the laboratory. Survival of adults caged in groups and supplied with a 10% sugar solution exceeded 80% after 30 days at 15 and 23°C. When kept individually in small gelatin capsules at 3°C, survival was good only up to 15 days. The gelatin capsules, however, allowed easier handling of individual parasites without disturbing the entire group.

Résumé

On a testé différentes températures pour l’élevage en laboratoire de Pteromalus puparum (L.). La survie des adultes encagés en groupes et ayant accès à une solution de 10% de sucre dépassait 80% après 30 jours à 15 et 23°C. La survie d’individus gardés isolés dans de petites capsules de gélatine à 3°C fût bonne jusqu’à 15 jours seulement. Cependant le maintien en capsule facilitait la manipulation des parasites individuels tout en évitant de déranger les autres individus du groupe.
